LOUIS C. SCHNEIDER, OF MITTWEIDA, GERMANY.

MACHINE FOR MAKING CARD-CLOTHING.

SPECIFICATION forming part of Letters Patent No. 662,469, dated November27, 1900. Application filed June 25, 1900- Serial No. Ely 1:17. lNOmodel-l To ctZZ whom it may concern:

Be it known that I, LOUIS O. SCHNEIDER, a subject of the King of Saxony,and a resident of Mittweida, Kingdom of Saxony, German Empire, haveinvented new and useful Improvements in Machines for Making Gard-Olothing, of which the following is a specification.

My invention relates to a machine for the manufacture of card-clothing,and has for its object to produce an organism which will bend the rearportion of a staple card-tooth structure so as to produce a bend orcurve in that portion of the staple which is embedded in the base orbody portion of the card-clothing and to likewise produce a forwardbending of the card-teeth, which constitute the working surface of thecard-clothing.

My invention therefore consists in the organisms of mechanism wherebythe above mentioned results are produced; and to a limited extent myinvention consists in combining with the said mechanism any desiredconstruction of mechanism for severing and feeding staple-blanks andforming up the same into staples.

My invention will be understood by referring to the accompanyingdrawings, in which I have shown a sufficient number of parts of acard-clothing machine to illustrate my invention.

In the drawings, Figure 1 is a plan View of the organisms for formingbending, and

inserting the staple and for bending the cardteeth. Fig. 2 is a similarplan View showing the parts in their advanced positions during theoperations of inserting the staple and bending over the card-teeth. Fig.3 is a side elevation of the structure with the parts in the positionshown in Fig. 1. Fig. 4 is a side View similar to Fig. 3, showing theparts in an intermediate position with the staple ready for insertion;and Fig. 5 is a side view of the parts in the position shown in Fig. 2.

In the drawings, 0 is a yoke or swinging frame carrying a bifurcatedhead I). The swinging yoke c carries pivoted thereto a lever 61, whoserear end is operated upon by a cam 71., which rear end is held againstthe cam by the spring g. The front end of the arm 11 has affixed theretoan adjustable arm e, which carries a bending device or finger f,

which is adapted to bend the rear end of the staple. Thehorizontally-pivotedjaws 7t serve to form up the staple over the head oranvil b and also to guide--the same when it is inserted into the bodyportion Z of the card clothing.

t'is an oscillating tongue or jaw, which is adapted to grip the rear barof the staple against the anvil I) while the bendingof the rear portionof the staple is being effected. In order to prevent the points of thestaple from being bent upward, a spring-actuated reciprocating pin it,carried in a bracket m, comes into such position as to prevent theupward tilting of the points of the staple. This pin '22 is providedwith a cam 0, which is acted upon by an arm q, carried on an arm 19 ofthe yoke 0, when the parts are given a forward motion to insert thestaple in the body portion of the card-clothing, so that at this timethe pin 92 will be drawn back out of the way, as shown in Fig. 2. Acurved needle or needles ctis or are provided for the purpose ofpiercing the curved holes through which the staple is inserted. Thepoints of the staple which constitute the teeth of the card-clothing aregiven a forward bend by means of the bending books or devices r, theanvil t being provided to assist in the bending and a guide U to guidethe body portion Z of the card-clothing. The wire may be fed and severedby the usual feeding and severing devices 8 it and may be bent up into astaple in any desired manner. The operation of the structure will beobvious from studying the positions of the various parts in thedifferent views of the drawings, it being understood that the staple isfirst formed, is then gripped between the jaw 7 and the head or anvil b,an d is thereupon bent by the descent of the fingerf, whereuponfan d 6rise successively and the forward motion of the parts serves to insertthe staple into the body portion of the card-clothing, the staple beingguided by the jaws 7c and thrust home by the jaw 2', whereupon the hooksr descend and bend the card-tooth over the anvil 75. Thus the effect ofthe first operation upon the completed staple is to bend the rearportions of the body portion or legs thereof out of the normal plane ofthe staple, and the effect of the second operation is to bend the legsto form the knees.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a machine for forming and inserting staples into the body ofcard-clothing, the combination of means for bending the rear portion ofa completed staple out of the normal plane of the body portionthereof,staple-inserting means, and tooth-bending means, as set forth.

2. The combination With a curved piercing device a for piercinga curvedhole in the body portion of a card-clothing, with means for bending therear portion of a staple and for inserting the same in the body portionof the card-clothing.

3. The combination with Wire severing and feeding devices, ofstaple-forming devices,-

means for bending the rear portion of the staple out of the normal planeof the staple, a staple-inserting device adapted to insert the said bentstaple into the body portion of the card-clothing and means for bendingthe staple leg or legs to form a knee or knees.

4. In a machine for making card-clothing, the combination of means forlaterally bending the rear portion of a staple out of the plane of thestaple, means for maintaining the staple-points in position for entryinto the cardclothing body portion, and means for inserting the stapleinto the said body portion.

5. In a machine for making card-clothing, the combination of means'forforming the staple, means for laterally bending the rear portion of saidstaple out of the normal plane of the staple, means for inserting thesaid staple into the body portion of a card-clothing, and means forbending over the staple-points.

6. In a machine for making card-clothing, the combination ofindependently-moving staple grasping and bending means adapted to imparta lateral bend to the staple, means for effecting the insertion of thesaid staple into the body of card-clothing, and means for guiding thebody portion into position to receive the staple.

7. In a machine of the character described, the combination of stapleforming and guiding jaws is combined with staple forming and graspingmeans 2', b, a device ffor laterally bending the rear portion of thestaple, and

means for producing a forward movement of the staple forming, graspingand bending devices to effect the insertion of the staple into the bodyportion of card-clothing.

8. In a machine for making card-clothing, the combination of means forimparting alateral bend to a staple, means for maintaining thestaple-points in position for entry into the body portion of thecard-clothing, and automatic means for effecting the insertion of thestaple into the said body portion and for removing thestaple-point-maintaining means out of the Way during the movement of theinsertion of the staple.

' 9. In a machine of the character described, the combination of meansfor piercing curved holes, combined with staple-forming means and meansfor producing a lateral bend in the staple and staple-inserting means.

' 10. In a machine for making-card-clothing the combination ofstaple-forming means,
